Layers of the Atmosphere
This layer is closest to Earth, contains 78% Nitrogen, and is where all weather occurs.
The Troposphere
This type of heat transfer occurs through direct contact with a heat source.
Conduction
Represented by blue triangles, this front brings thunderstorms followed by cool, clear skies.
Cold Front
This term describes what is happening in the air right now at a specific time and place.
Weather
Fuels like oil, coal, and natural gas are known as ...
Fossil Fuels
Known as the coldest layer of the atmosphere, this is where meteors typically begin to burn up.
The Mesosphere
This describes the transfer of heat through the movement of fluids, where warm parts rise and cool parts sink.
Convection
This front occurs when a warm air mass replaces a cold one and is shown on a map as a red line with semicircles.
Warm Front
This climate type is hot and humid, located near the equator, and is home to primates and reptiles.
Tropical
This is the process where gases in the atmosphere trap heat to keep Earth warm, acting like a blanket.
The Greenhouse effect
Most planes fly in this layer, which contains the Ozone layer that protects us from UV rays.
The Stratosphere
This type of air has molecules spread further apart, holds more moisture, and results in lower air pressure.
Warm Air
These blow onshore during the day when the land heats up faster than the water.
Sea Breeze
In the water cycle, this is the phase where water vapor cools down to form clouds.
condensation
: These are the two primary greenhouse gases mentioned that contribute to global warming.
Carbon Dioxide and Methane
This layer has the lowest air pressure and represents the outermost boundary before entering space.
The Exosphere
This is the transfer of energy through electromagnetic waves, such as UV rays, and does not require a medium to travel through.
Radiation
This type of front occurs when a cold and warm front meet but neither moves, often resulting in prolonged rain or snow.
Stationary Front
In the nitrogen cycle, this is the process where bacteria in the soil transform nitrogen into a form plants can use.
Fixation
Ocean tides—the rise and fall of sea levels—are caused by this celestial body's gravity.
The Moon
While it's the hottest layer due to direct solar absorption, it is also where the International Space Station orbits.
The Thermosphere
Defined as the amount of "stuff" or mass packed into a specific amount of space.
Density
This complex front occurs when a fast-moving cold front overtakes a warm front, lifting the warm air off the ground.
Occluded
These are the two primary factors, along with wind, that cause the movement of ocean currents.
temperature and salinity
This cycle involves plants taking in CO2 to release a gas that humans and animals need to breathe.
